Abstract

Apparatus and methods for assessing tissue characteristics such as the dimensions and volume of an osteolytic lesion are disclosed. The apparatus may utilize ultrasound to provide visual and volumetric feedback related to a lesion or other tissue. Further the apparatus may be utilized to determine whether the lesion has been completely removed and filled with the appropriate amount of graft material.

Claims

AMENDED CLAIMS received by the International Bureau on 24 April 2008 (24.04.08)WHAT IS CLAIMED IS:
1. A coupling apparatus for use with an ultrasonic probe in evaluation of a lesion of a bone having an artificial implant, comprising; a coupling attachment having a body formed of an ultrasonic conductive material, said body having an internal wall defining a cavity adapted to receive a portion of the ultrasonic probe and an external surface, wherein said external surføce is configured to engage a substantial portion of the artificial implant
2. The apparatus of claim 1, wherein the artificial implant is an acetabular cup.
3. The apparatus of claim 1, wherein said coupling attachment mates with a handheld ultrasound device for detecting indicators of a lesion.
4. The apparatus of claim 3, wherein the hand-held ultrasound device removably mates with the coupling attachment,
5. The apparatus of claim 4. wherein the coupling attachment is disposable.
6. The apparatus of claim 3, wherein at least a portion of the surface of the coupling attachment is malleable to conform to the implant
7. The apparatus of claim 3, wherein the artificial implant has an internal socket and said external surface of the coupling attachment is sized to mate with a specific size socket of the artificial implant
8. The apparatus of claim 6, wherein the malleable surface of the coupling attachment is adapted for conductive contact with the artificial implant.
9. The apparatus of claim S, wherein the artificial implant is adapted to transmit or receive ultrasound signals when in conductive contact with the coupling attachment.
10. The apparatus of claim 8, further including a fjowable coupling media, wherein the conductive contact between the coupling attachment and the artificial implant is facilitated by a coupling media.
11. The apparatus of claim 10, wherein the coupling media is a liquid.
12, The apparatus of claim 7, further including a plurality of coupling attachments of varying sizes.
13, The apparatus of claim 3, wherein a portion of the hand-held ultrasound device is disposable.
14. A system for providing visual feedback of a lesion of a bone, comprising: a hand-held ultrasound device adapted to transmit a signal into a bone, receive reflected signals indicative of inconsistency in the bone and produce a corresponding output signal; a processor in communication with said hand-held ultrasound device and adapted to receive said output signal, said processor configured to formulate a 3-D model of the lesion based on the output signal, said processor providing a display signal; and a display device in communication with said processor and responsive to said display signal to display at least one view of the 3-D model ofthe lesion.
